In the past, ocean carbon data was sparse, mostly gathered by ships. But the future of monitoring belongs to robot floats that deliver real-time data across vast oceans — even in the remote Antarctic Southern Ocean.
The Great Barrier Reef is experiencing a sixth mass bleaching event, the marine park’s authority confirmed today after completing aerial surveys of the region. This is the fourth time the…
In 2010, an influx of cold air blew over the lower Florida Keys, chilling the subtropical waters to temperatures as low as 11° Celsius, or 52° Fahrenheit. The coral reefs…
On May 25, 1946, the United States detonated the first underwater nuclear bomb at Bikini Atoll in the Marshall Islands to see what kind of damage it would cause. This…
Unlike boundaries on the land, the ocean is contiguous — fish move and transcend international waters as they please, without bothering about jurisdictions. As long as ocean temperatures remain generally…
ACCRA, Ghana — White waves collide in a crash where the Volta River meets the Atlantic Ocean near Ada Foah. Warm, tropical air hovers over Ghana's coastline – but as…
Coral reefs are a unique and biodiverse natural ecosystem and economic keystones for many communities and nations. They only cover about 0.2% of the ocean floor but support 25% of…
When conservation ecologist Rob Harcourt went surfing off the coast of Sydney, Australia, he immediately knew the water was warmer than usual. “We had at least 23 [degrees Celsius, or…
For years, Joaquim Garrabou donned scuba gear and dove into the waters of the Scandola Marine Reserve in Corsica to find a paradise. Twenty meters (66 feet) beneath the surface,…
In 2015 and 2016, record ocean temperatures triggered coral bleaching events around the world — from Hawai‘i to the Caribbean to Australia — turning once-healthy polyps into ghostly skeletons. But…
Escalating ocean temperatures stemming from climate change are devastating the world’s tropical coral reefs. In response to the stress, corals, which are animals, sometimes unceremoniously jettison the algae that live…
The ocean is now warmer than it’s ever been in recent history, according to a new study. And this isn’t the first time such a record has been set. For…
In 2008, a team of researchers boarded an expedition vessel and set sail for the anchovy-rich waters off the coast of Peru. They were searching for a place to extract…
Ten countries in the western Indian Ocean are banding together to create a network of marine conservation areas under the banner of the Great Blue Wall. The idea is to…
JAKARTA — Indonesia is launching a program to make the country’s ports more environmentally friendly in an effort to reduce its carbon emissions and protect the marine ecosystem. The so-called…
As climate change worsens, sea turtles on the U.S. Atlantic and Gulf seaboards, and in other coastal areas around the world, are increasingly at risk from cold-stunning events. But rescuers often await.
All seven sea turtle species are already endangered. Now humanity’s overshoot of planetary boundaries — climate change, ocean acidification, pollution and more — is upping the ante. Can turtles, people and conservation adapt?
Scientists have completed the first-ever global, high-resolution map of the world’s shallow tropical coral reefs. The map is part of the Allen Coral Atlas, an open-access, user-friendly coral reef monitoring…
In July 2021, the U.S. Fish & Wildlife Service announced that 866 West Indian manatees (Trichechus manatus) had died in the state of Florida in the first seven months of…
On one of the first dry, hot days of summer, Rachel Langley walks past farmhouses and tractors, heading for the edge of the Colne Estuary in Essex, U.K. She’s on…
Researchers are seeking to pinpoint climate change “tipping points,” but defining what that means exactly, when it will come, and what makes it happen, is unimaginably difficult when faced with the chaotic complexities of a vast Earth biome.
Jeffrey Marlow says we should be thinking more about microbes — those teensy, tiny organisms that inhabit just about every part of the biosphere, but are only visible under the…
While coral reefs throughout the Indo-Pacific region have been bleaching in response to rising sea temperatures, the reefs around Marovo Lagoon in the Solomon Islands have mostly kept their color.…
Simple mathematical models suggest overshooting Paris climate accord emission targets for a short time won’t immediately trigger some environmental tipping points, allowing time to act.
In 1987, world leaders signed the Montreal Protocol in an attempt to curb the amount of chlorofluorocarbons (CFCs) and other harmful chemicals being released into the atmosphere, which have been…
A new study has found that sea levels are rising faster than expected, which would put 40% of the world’s population living in coastal regions at elevated risk. Published Feb.…
When scientists first discovered glass sponge reefs in British Columbia’s waters in the late 1980s, they couldn’t have been more surprised. Prior to this, they believed that glass sponge reefs…
CAPE FERGUSON, Australia — In a lab on Australia’s east coast, scientists are concocting what they hope will be the solution to the steadily worsening problem of coral bleaching. Few…
Coral reefs are often called the “rainforests of the sea” because they harbor some of the highest levels of biodiversity of any ecosystem in the world. But as sea temperatures…
BEIRUT, Lebanon — A hidden invasion is taking place beneath the waves of the Mediterranean Sea. In recent years, scientists have recorded more than 700 alien species in Mediterranean waters,…
